About This Scan
Two weak-open signals together: the stock opened 1% to 15% below the previous close, and the open is also the day's high, so price has not traded above its first print. Sellers took control from the start. This scan lists NSE stocks meeting both rules with price below the open, on Rs 5 Cr of last-session turnover. It is rare by design and can be short on a day the market gaps up. The mirror scan is Gap Up and Open = Low. For each rule alone, see Open = High (Sell Side) and Gap Down Stocks Today.

How To Use This Scan
- •Check the reason for the gap. A gap on results or news behaves differently from a gap with no news.
- •The open is the usual stop reference, since the idea fails if price trades above it. Gaps above 15% are skipped as likely corporate actions.
- •The list is short early and later in the day. Re-run it during the session. This scan has not been back-tested for an edge.
Frequently Asked Questions
Why combine a gap with open = high?
A gap shows supply before the open. Open = high shows it held through the session. Together they filter out gaps that were bought at once.
Why is the list sometimes short?
On days when the market gaps up, few stocks gap down and hold their open as the high.
Which open does it use?
The official daily open, so the list is the same on every interval.
